428426 ÷ 51 
Let's see how many times 51 fits into 428426.

On to step 1:
51 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 51

Step 2:
If we divide 42 by 51, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 51

Step 3:
The number 51 fits into 428 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 408 from 428, we get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 51

Going ahead to step 4:
204 divided by 51 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 84.0
If we subtract 204 from 204, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 51

Moving on to step 5:
2 divided by 51 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 840.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 51

Let's proceed to step 6:
51 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 8400.0
The remainder is 26 after subtracting 0 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8400.5
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 51, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8400.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 51 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 8400.509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
When dividing 410 by 51, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8400.5098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8400.5098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
If we divide 200 by 51, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 8400.509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 13:
If we divide 470 by 51, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 8400.5098039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8400.50980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 8400.50980392, and the remainder is 8e-09.
